Efficacy of water infusion combined with defoamers in colonoscopy.

Background: Currently, colonoscopy still needs continuous optimization and exploration of novel alternative approaches to enhance the experience of patients during colonoscopy.

Aim: To analyze the efficacy of water infusion combined with defoamers in colonoscopy.

Methods: This study included 97 patients undergoing colonoscopy from January 2024 to June 2024. The participants were categorized into two groups, namely, the control group (n = 47), who underwent conventional colonoscopy, and the experimental group (n = 50), who received colonoscopy using water injection combined with defoamers. A comparative analysis was then conducted on the disease detection rate (colonic polyps, colonorrhagia, colonic ulcers, colonic mucosal lesions, and others), colonoscopy duration, abdominal pain [visual analog scale (VAS)], Boston bowel preparation scale (BBPS), self-rating anxiety scale (SAS), bowel preparation comfort, complications (intestinal perforation, bleeding, nausea and vomiting, abdominal pain, and abdominal distension), and patient satisfaction.

Results: The experimental group demonstrated a significantly higher total disease detection rate, BBPS scores, and patient satisfaction compared with the control group. Further, the research group exhibited shorter colonoscopy duration, lower VAS and SAS scores and total complication rate, and better patient comfort and satisfaction.

Conclusion: These results indicate that the combination of water injection and defoamers exhibited an overall better therapeutic effect than conventional colonoscopy, mainly reflected in higher disease detection rate, faster examination efficiency, lower abdominal pain, anxiety, and complication incidences, and significantly better bowel preparation, comfort, and patient satisfaction.
